BACKGROUND
We were instructed by our client to attend a residential property in the Coventry area to carry out a Japanese Knotweed Survey. During consultation our client advised that they had suspected Japanese Knotweed on a piece of land they had recently purchased. Our client advised that they have future plans to possibly develop the area of land into a driveway.
SITE SURVEY
Japanese Knotweed was identified within the boundaries of the property and on the neighbouring property (newly acquired paddock) which is now owned by the subject property owner.
Our client expressed they may wish to instate a driveway, which would be through the Japanese Knotweed location. If the development plans are proceeded, the Japanese Knotweed would require excavation and not a 5 year herbicide treatment plan.
All ground debris found at time of survey and shed needed to be removed prior to excavation.
Plant machinery would excavate approximately 6m2 resulting in approximately 12m3 of soils to be removed. This would require 2 technicians, plant machinery and operative for 2 days. Backfill material would be required for the excavation zone.
Before works could commence, a soil analysis would be required in order for landfill to accept the soils containing JKW.
Should the client decide against the decision to instate a driveway, a 5 year herbicide management plan would be sufficient. The JKW area and a 1metre boundary around the JKW would require non disturbance for the duration of the management plan and warranty period. A quotation for excavation and
herbicide management plan was therefore provided to the client.
